Standard type belts force you to use limited sizes. Depending on your physique, the belt is either too tight or too loose. These straps offer a very fine adjustment to be comfortable without suffocating you. I just can't go back to my old style thongs where you have to lick between the holes and hope they aren't too tight or too loose. Since I lost a lot of weight, these belts can also be suitable for various weight loss or gain within reason. Outstanding quality and design!
